Anwendungen

Used in the laboratory as LB (Lithium borate) buffer for gel electrophoresis of DNA and RNA. Employed in the borax fusion method to modify mineral powder samples for analysis by WDXRF (Wavelength Dispersive X-Ray Fluorescence) Spectroscopy. Acts as an ingredient in the manufacture of glasses and ceramics. Useful fod dissolving basic oxides such as CaO and MgO. A mixture of lithium metaborate and lithium tetraborate is useful for dissolving most of the inorganic oxides to enable spectrochemical analysis.

Bemerkungen

Hygroscopic in nature. Incompatible with strong oxidizing agents and strong acids.
